Title: Transmitting and receiving circuits for wave transmission systems
IPC: H01P1/12
Filed: 1946-11-15
Abstract: 621,593. Discharge apparatus. WESTERN ELECTRIC CO., Inc. Nov. 15, 1946, No. 33978. Convention date, Jan. 30, 1943. Addition to 575,432. [Class 39 (i)] [Also in Group XL (c)] Terminal apparatus of the type described in the parent Specification for an electric signalling system comprises a coaxial line or wave-guide connecting a transmitter and receiver to a common channel (e.g. an aerial), and a pair of cavity resonators coupled to the coaxial line or wave-guide so as to block the receiver during transmission and the transmitter during reception. Each resonator contains a gas discharge device, the couplings of the resonators to the coaxial line or wave-guide being linearly spaced a distance equal to a small odd multiple of a quarter wavelength (Fig. 6). In an alternative arrangement employing coaxial lines only one resonator associated with the receiver is employed (Fig. 2, not shown). The gas discharge device connector across the resonant chamber associated with the receiver is adapted to discharge in response to the resonant voltage applied to the cavity by the outgoing waves from the transmitter to effectively short-circuit the cavity and thus the input to the receiver, but to remain in the undischarged condition in response to an incoming wave, whilst that associated with the transmitter is adapted to discharge only during incoming waves. The cavity resonator, Fig. 3, comprises an upper rectangular box portion 8 and lower cylindrical portion 9, mounted slidably on a coaxial line 1. The portion 9 has a small slot 11 in one side opposite to and opening into the slot 5 in the outer coaxial conductor 4, so as to provide a window electrically coupling one side of the cavity to the line 1. Tuning of the resonator is effected by means of the slidable portion 13 and screw 12. The receiver coupling 2 is attached directly opposite the slot 11. Connected across the cavity of the portion 9 is a gas discharge tube 15, having electrode 16 and 17 forming the spark-gap, and an auxiliary electrode 18. The electrode 18 is maintained at a fixed negative potential with respect to the electrode 16 and 17 and is employed to reduce the leakage power at the initiation of the firing of the tube. Specification 589,023 and U.S.A. Specification 2,063,342 are referred to.

Abstract: 1401146 Fire alarm systems CERBERUS AG 17 July 1973 [17 July 1972] 34094/73 Headings G4H and G4N A fire alarm system comprises one or more parallel connected detector units having a voltage saturation characteristic in the alarm condition, and a central station with a current limiter and a voltage sensor. Detector unit.-Any sensor such as optical, temperature, or smoke type may be used. As shown Fig. 3, a conventional ionization smoke detector actuates a bi-stable switch 18, 19, to (i) energize a local indicator lamp 26, and (ii) effectively connect Zener diode 28 across the lines (using Zener controlled transistor 27) thereby providing a voltage-saturation-characteristic for the detector, and maintaining a constant voltage across the lamp independent of line current. Alternatively a transistor regulator 43 may be used Fig. 4 (not shown). Central station.-The supply voltage U V  passes through current limiting transistors 46, 47 to the line 62 connecting to the detector units. The line voltage U M  is monitored by transistor 53 having a reference Zener diode 57 and arranged so that it is conducting at the saturation voltage of the detector. Thus a line short-circuit causes transistor 53 to block removing the signal to AND-gate 59 and fault indicator 61. A "fire-signal" from a detector unit draws increased line current causing transistor 47 (in the limiter circuit) to conduct and apply the second signal to AND-gate 59 thereby operating the alarm 60. Additional features (i) the alarm operation may apply pulses 76 to transistor 48 to modulate the line current and causes the local detector lamp to flash, (ii) an end-of-line oscillator Fig. 6 (not shown) of the kind described in Specification 1,319,615 may be used, and signals therefrom are amplified by the current limiters 46, 47 and applied through capacitor 78 to operate pulse detector 77, which controls fault indicator 61 to show a line open-circuit, (iii) stations may be located by the voltage U M  if the lines are of different lengths.

Abstract: 1061927 Making wire UNITED KINGDOM ATOMIC ENERGY AUTHORITY 28 Aug 1963 [7 Sept 1962] 34437/62 Headings H1A A5 and A4D A super-conducting filament, of small enough diameter that it will exhibit super-conductivity in a magnetic field greater than the critical field, is formed by including it in a suitable carrier which is then subjected to a wire drawing or swaging process to reduce its diameter. The diameter of such a filament should be less than 0À1 micron. In one embodiment a cylindrical billet of molybdenum is drilled with axial holes into which rods of niobium are inserted. The composite billet is then reduced in diameter by swaging and or drawing. The wire is then cut into lengths which are then bundled and sheathed by extruding molybdenum over it. The diameter is then reduced in the same manner as before, and so on until the requisite filament diameter is obtained. In a second method a bundle of niobium wires electro-plated with molybdenum is treated in the same manner. The carrier should be an inhibitor of super-conductivity (such as molybdenum) or an insulator. The super-conducting filaments may also be of vanadium or led or a niobium-zirconium alloy.

Inventor: MOTHERSOLE PETER LEONARD
IPC: H03K4/43
Filed: 1964-08-24
Abstract: 1,099,343. Frame time-base circuits. MULLARD Ltd. May 17, 1965 [Aug. 24, 1964], No. 34521/64. Headings H3P and H3T. Irregular triggering of a frame time-base circuit on alternate frames of an interlaced scan is avoided by causing the frame oscillator to operate a switch at the commencement of the flyback period thereby isolating the oscillator from the sync. pulses during the flyback. In Fig. 1 the switch comprises a diode D1 which conducts when the oscillator is triggered and short-circuits the sync. pulses developed across R2, thereby clamping the potential at C close to zero. The time constant of C2R2 is chosen so that during the frame scan when V1 is cut off, the diode conducts for about half the line scan period on 405 lines and three quarters on 625 lines. The oscillator conducts for a period longer than the frame sync. pulse and thus timing errors at the end of this pulse are also avoided. As shown V1 is part of a multivibrator, but it may be a blocking oscillator, and the invention is also applicable to transistor circuits.
